前提：关闭防火墙
命令：systemctl status firewalld 查看防火墙状态
systemctl stop firewalled 临时关闭防火墙
systemctl disable firewalld 彻底关闭防火墙
解压文件 命令：cd /opt/module/
tar -zxvf apache-zookeeper-3.5.5-bin.tar.gz
然后输入命令：cd /opt/module/apache-zookeeper-3.5.5-bin/
创建文件夹 命令： mkdir data mkdir log
拷贝文件：cd conf
cp zoo_sample.cfg zoo.cfg
配置文件更改内容
dataDir=/opt/module/apache-zookeeper-3.5.5-bin/data
dataLogDir=/opt/module/apache-zookeeper-3.5.5-bin/log
并在最后输入
server.0=192.168.1.100:2888:3888
server.1=192.168.1.101:2888:3888
server.2=192.168.1.102:2888:3888
然后创建服务器myid
cdc /opt/module/apache-zookeeper-3.5.5-bin/data
touch myid
并在里面输入 0
在192.168.1.101中输入 1
在192.168.1.102中输入 2
集群拷贝
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop101:/opt/module/apache-zookeeper-3.5.5-bin
scp -r /opt/module/apache-zookeeper-3.5.5-bin root@hadoop102:/opt/module/apache-zookeeper-3.5.5-bin
集群系统环境变量添加 命令： vi /etc/profile
export ZOOKEEPER_HOME=/opt/module/apache-zookeeper-3.5.7-bin
export PATH=$PATH:$ZOOKEEPER_HOME/bin
然后esc:wq
保存系统环境变量 命令： source /etc/profilee
关闭防火墙命令：systemctl stop firewalled
进去每个节点启动 命令： cd /opt/module/apache-zookeeper-3.5.5-bin
zkServer.sh start
zkServer.sh status
最后连接验证命令： zkCli.sh -server hadoop100:2181
